you can use gazelle.com, key exchange. you can use ebay. that's where i found you get the best prices. but what you need to know is they lose value the longer they sit in the drawer. so, sell them now. >> great advice. big question. how do i get the new gadget to work? >> right. >> i'm dying to use it. my kids go through this. they get this thing and i'm so scared for that. >> right. you have lots of different services that are available to you. you know about the geek squad. that's a subscription service. if you get a new mac, you can go to apple and get their one-to-one training services, where they give you weekly lessons for $99 a year. my best advice, find a geeky kid in the neighborhood. the price is right. they're more flexible. and they'll be responding to your ever embarrassing question. >> i want you to get to your last test. >> the one thing i recommend on christmas, is to bust out the freezer bags and the sharpies. every new gadget. you label what it is. the warranty, the instructions, extra cables and everything you get with it
